Ingredients for Sesame Seed and Árbol Chilli Salsa

  • 1 1/2 tablespoons vegetable oil

  • 60ml minced onion

  • 2 large garlic cloves

  • 35g sesame seeds, toasted

  • 70g dried árbol chillies

  • 4 large tomatillos, husked and rinsed

  • Salt and freshly ground black pepper

How to make Sesame Seed and Árbol Chilli Salsa

Heat the vegetable oil in a large heavy sauté pan over medium-high heat. Add the onion and garlic cloves and sauté for 5 minutes, or until the garlic is golden brown. Add the sesame seeds and árbol chillies and cook for 5 minutes, or until the chillies are darkened in spots.

Meanwhile, heat a medium-size heavy sauté pan over high heat. Add the tomatillos and cook, turning them frequently, for 10 minutes, or until they are pale green and blackened in spots. Add the tomatillos to the chilli mixture in the pan, pressing on them with a spatula to break them apart and release their juices. Cook for 5 minutes to blend the flavours. Remove from the heat and let cool slightly.

Transfer the contents of the pan to a blender, and add 350ml water. Blend until the salsa is smooth. Season to taste with salt and pepper. Cool to room temperature, and then serve.
